Quality Control

Our o-Ethyl Ethylchloridothiophosphonate is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity and potency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its sensitivity to moisture and potential for oxidation under air, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature is 2-8°C.
